With the growth of each technology, the related security issues become of particular importance. Taking advantage of this technology in different environments with numerous features put at our disposal, there arises an increasing need to address the security threats. Being IP-based and playing a signaling role in VOIP networks, Session Initiation Protocol (SIP) lets the invaders use weaknesses of the protocol to disable VOIP service. One of the most important threats is denial of service attack, a branch of which in this article we have discussed as flooding attacks. These attacks make server resources wasted and deprive it from delivering service to authorized users. Distributed denial of service attacks and attacks with a low rate can mislead many attack detection mechanisms. In this paper, we introduce a mechanism which not only detects distributed denial of service attacks and low rate attacks, but can also identify the attackers accurately. We detect and prevent flooding attacks in SIP protocol using Shannon (FDP-S), Renyi (FDP-R) and Tsallis (FDP-T) entropy. We conducted an experiment to compare the percentage of detection and rate of false alarm messages using any of the Shannon, Renyi and Tsallis entropy as a measure of disorder. Implementation results show that, according to the parametric nature of the Renyi and Tsallis entropy, by changing the parameters, different detection percentages and false alarm rates will be gained with the possibility to adjust the sensitivity of the detection mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=VOIP%20networks" title="VOIP networks">VOIP networks</a>, <a href="https://publications.waset.org/abstracts/search?q=flooding%20attacks" title=" flooding attacks"> flooding attacks</a>, <a href="https://publications.waset.org/abstracts/search?q=entropy" title=" entropy"> entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20networks" title=" computer networks"> computer networks</a> </p> <a href="https://publications.waset.org/abstracts/28214/sip-flooding-attacks-detection-and-prevention-using-shannon-renyi-and-tsallis-entropy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28214.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">405</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Estimating Housing Prices Using Automatic Linear Modeling in the Metropolis of Mashhad, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Rahim%20Rahnama">Mohammad Rahim Rahnama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Market-transaction price for housing is the main criteria for determining municipality taxes and is determined and announced on an annual basis. Of course, there is a discrepancy between the actual value of transactions in the Bureau of Finance (P for short) or municipality (P´ for short) and the real price on the market (P˝). The present research aims to determine the real price of housing in the metropolis of Mashhad and to pinpoint the price gap with those of the aforementioned apparatuses and identify the factors affecting it. In order to reach this practical objective, Automatic Linear Modeling, which calls for an explanatory research, was utilized. The population of the research consisted of all the residential units in Mashhad, from which 317 residential units were randomly selected. Through cluster sampling, out of the 170 income blocks defined by the municipality, three blocks form high-income (Kosar), middle-income (Elahieh), and low-income (Seyyedi) strata were surveyed using questionnaires during February and March of 2015 and the information regarding the price and specifications of residential units were gathered. In order to estimate the effect of various factors on the price, the relationship between independent variables (8 variables) and the dependent variable of the housing price was calculated using Automatic Linear Modeling in SPSS. The results revealed that the average for housing price index is 788$ per square meter, compared to the Bureau of Finance’s prices which is 10$ and that of municipality’s which is 378$. Correlation coefficient among dependent and independent variables was calculated to be R²=0.81. Out of the eight initial variables, three were omitted. The most influential factor affecting the housing prices is the quality of Quality of construction (Ordinary, Full, Luxury). The least important factor influencing the housing prices is the variable of number of sides. The price gap between low-income (Seyyedi) and middle-income (Elahieh) districts was not confirmed via One-Way ANOVA but their gap with the high-income district (Kosar) was confirmed. It is suggested that city be divided into two low-income and high-income sections, as opposed three, in terms of housing prices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automatic%20linear%20modeling" title="automatic linear modeling">automatic linear modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=housing%20prices" title=" housing prices"> housing prices</a>, <a href="https://publications.waset.org/abstracts/search?q=Mashhad" title=" Mashhad"> Mashhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a> </p> <a href="https://publications.waset.org/abstracts/42519/estimating-housing-prices-using-automatic-linear-modeling-in-the-metropolis-of-mashhad-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42519.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">255</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> Service-Based Application Adaptation Strategies: A Survey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahba%20Paktinat">Sahba Paktinat</a>, <a href="https://publications.waset.org/abstracts/search?q=Afshin%20Salajeghe"> Afshin Salajeghe</a>, <a href="https://publications.waset.org/abstracts/search?q=Mir%20Ali%20Seyyedi"> Mir Ali Seyyedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Rastegari"> Yousef Rastegari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Service Oriented Architecture (SOA) allows modeling of dynamic interaction between incongruous providers, which enables governing the development of complex applications. However, implementation of SOA comes with some challenges, including its adaptability and robustness. Dynamism is inherent to the nature of service-based applications and of their running environment. These factors lead to necessity for dynamic adaptation. In this paper, we try to describe basics and main structure of SOA adaptation process with a conceptual view to this issue. In this survey, we will review the relevant adaptation approaches. This paper allows studying how different approaches deal with service oriented architecture adaptation life-cycle and provides basic guidelines for their analysis, evaluation and comparison. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=context-aware" title="context-aware">context-aware</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20adaptation" title=" dynamic adaptation"> dynamic adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20services" title=" quality of services"> quality of services</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20oriented%20architecture" title=" service oriented architecture"> service oriented architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20based%20application" title=" service based application"> service based application</a> </p> <a href="https://publications.waset.org/abstracts/7201/service-based-application-adaptation-strategies-a-survey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7201.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">455</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> Molecular Communication Noise Effect Analysis of Diffusion-Based Channel for Considering Minimum-Shift Keying and Molecular Shift Keying Modulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Azari">A.

The previous analysis, however, has concentrated on end-to-end communication model with no separate modelings for propagation channel and noise. By considering a separate signal propagation and noise model, the design and implementation of an optimum receiver will be much easier. In this paper, we justify consideration of a separate additive Gaussian noise model of a nano-communication system based on the molecular communication channel for which are applicable for MSK and MOSK modulation schemes. The presented noise analysis is based on the Brownian motion process, and advection molecular statistics, where the received random signal has a probability density function whose mean is equal to the mean number of the received molecules. Finally, the justification of received signal magnitude being uncorrelated with additive non-stationary white noise is provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=molecular" title="molecular">molecular</a>, <a href="https://publications.waset.org/abstracts/search?q=noise" title=" noise"> noise</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion" title=" diffusion"> diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=channel" title=" channel"> channel</a> </p> <a href="https://publications.waset.org/abstracts/74407/molecular-communication-noise-effect-analysis-of-diffusion-based-channel-for-considering-minimum-shift-keying-and-molecular-shift-keying-modulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74407.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">279</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> The Effect of Explicit Focus on Form on Second Language Learning Writing Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keivan%20Seyyedi">Keivan Seyyedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Esmaeilpour"> Leila Esmaeilpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Jamal%20Sadeghi"> Seyed Jamal Sadeghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Investigating the effectiveness of explicit focus on form on the written performance of the EFL learners was the aim of this study.

This approach presents a generalization of the previously obtained results that made use of interpolating Jensen-type inequalities. Thus the monotonicity property is integrated with the Zipf-Mandelbrot law and applied to f-divergences for probability distributions that originate from the Csiszar divergence functional: Kullback-Leibler divergence, Hellinger distance, Bhattacharyya distance, chi-square divergence, total variation distance. The Zipf-Mandelbrot and the Zipf law are widely used in various scientific fields and interdisciplinary and here the focus is on the aspect of the mathematical inequalities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jensen%20functional" title="Jensen functional">Jensen functional</a>, <a href="https://publications.waset.org/abstracts/search?q=monotonicity" title=" monotonicity"> monotonicity</a>, <a href="https://publications.waset.org/abstracts/search?q=Csiszar%20divergence%20functional" title=" Csiszar divergence functional"> Csiszar divergence functional</a>, <a href="https://publications.waset.org/abstracts/search?q=f-divergences" title=" f-divergences"> f-divergences</a>, <a href="https://publications.waset.org/abstracts/search?q=Zipf-Mandelbrot%20law" title=" Zipf-Mandelbrot law"> Zipf-Mandelbrot law</a> </p> <a href="https://publications.waset.org/abstracts/107243/monotonicity-of-the-jensen-functional-for-f-divergences-via-the-zipf-mandelbrot-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107243.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> How to Enhance Performance of Universities by Implementing Balanced Scorecard with Using FDM and ANP </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neda%20Jalaliyoon">Neda Jalaliyoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Nooh%20Abu%20Bakar"> Nooh Abu Bakar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Taherdoost"> Hamed Taherdoost</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present research recommended balanced scorecard (BSC) framework to appraise the performance of the universities.

Conclusion: A combination of SIRS criteria and PCT levels is beneficial for the early sepsis diagnosis in emergency ward patients with a suspicious infection disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergency" title="emergency">emergency</a>, <a href="https://publications.waset.org/abstracts/search?q=prolactin" title=" prolactin"> prolactin</a>, <a href="https://publications.waset.org/abstracts/search?q=sepsis" title=" sepsis"> sepsis</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarkers" title=" biomarkers"> biomarkers</a> </p> <a href="https://publications.waset.org/abstracts/18189/procalcitonin-and-other-biomarkers-in-sepsis-patients-a-prospective-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18189.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">439</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> Location Detection of Vehicular Accident Using Global Navigation Satellite Systems/Inertial Measurement Units Navigator </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neda%20Navidi">Neda Navidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rene%20Jr.%20Landry"> Rene Jr. Landry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vehicle tracking and accident recognizing are considered by many industries like insurance and vehicle rental companies. The main goal of this paper is to detect the location of a car accident by combining different methods. The methods, which are considered in this paper, are Global Navigation Satellite Systems/Inertial Measurement Units (GNSS/IMU)-based navigation and vehicle accident detection algorithms. They are expressed by a set of raw measurements, which are obtained from a designed integrator black box using GNSS and inertial sensors. Another concern of this paper is the definition of accident detection algorithm based on its jerk to identify the position of that accident. In fact, the results convinced us that, even in GNSS blockage areas, the position of the accident could be detected by GNSS/INS integration with 50% improvement compared to GNSS stand alone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=driver%20behavior%20monitoring" title="driver behavior monitoring">driver behavior monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=integration" title=" integration"> integration</a>, <a href="https://publications.waset.org/abstracts/search?q=IMU" title=" IMU"> IMU</a>, <a href="https://publications.waset.org/abstracts/search?q=GNSS" title=" GNSS"> GNSS</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=tracking" title=" tracking"> tracking</a> </p> <a href="https://publications.waset.org/abstracts/72798/location-detection-of-vehicular-accident-using-global-navigation-satellite-systemsinertial-measurement-units-navigator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72798.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">234</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Geometric Continuity in the Form of Iranian Domes, Study of Prominent Safavid and Sasanian Domes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nima%20Valibeig">Nima Valibeig</a>, <a href="https://publications.waset.org/abstracts/search?q=Haniyeh%20Mohammadi"> Haniyeh Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Sadat%20Abdelahi"> Neda Sadat Abdelahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Persian domes follow different forms depending on the materials used to construct and other factors. One of the factors that shape the form of a dome is the geometric proportion used in the drawing and construction of the dome. Some commonly used proportions are revealed by analysing the shapes and geometric ratio of the monuments’ domes. The proportions are achieved by the proficiency of the skilled architects of the buildings. These proportions can be used to reconstruct damaged parts of the historical monuments. Most of the research on domes is about the historical or stability features of domes, and less attention is made to the geometric system in domes. Therefore, in this study, we study the explicit and implicit geometric proportions in Iranian dome structures for the first time. The study is done based on a literature review and field survey. This research reveals that the permanent geometric rules are perfectly used in the design and construction of the prominent domes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geometry%20in%20architecture" title="geometry in architecture">geometry in architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=architectural%20proportions" title=" architectural proportions"> architectural proportions</a>, <a href="https://publications.waset.org/abstracts/search?q=prominent%20domes" title=" prominent domes"> prominent domes</a>, <a href="https://publications.waset.org/abstracts/search?q=iranian%20golden%20ratio" title=" iranian golden ratio"> iranian golden ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=geometric%20proportion" title=" geometric proportion"> geometric proportion</a> </p> <a href="https://publications.waset.org/abstracts/149514/geometric-continuity-in-the-form-of-iranian-domes-study-of-prominent-safavid-and-sasanian-domes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">284</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> A FR Fire-Off with Polysilicic Acid for Pes/Co Blends</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raziye%20Atakan">Raziye Atakan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebru%20Celebi"> Ebru Celebi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gulay%20Ozcan"> Gulay Ozcan</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Soydan"> Neda Soydan</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Sezai%20Sarac"> A.

Polyester/Cotton (Pes/Co) blend fabrics were treated via pad-dry-cure process with this synthesized chemical. PVA (PR)-P-DCDA has shown that it is an effective flame retardant on the fabrics. In order to improve durable flame retardancy for cotton part of the blend, polysilicic acid and citric acid monohydrate auxiliaries were added in FR finishing bath at different concentrations. Flammability and characteristic properties of the sample were tested according to relevant ISO standard and procedures. To do so, ISO 6940 vertical flammability test, TGA, DTA, LOI and FTIR analysis have been performed. The obtained results showed that this new finishing formulation is a good char-forming agent for the PES/CO blends and polysilicic acid could be used for cellulosic blends with PVA (PR)-P-DCDA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flame%20retardancy" title="flame retardancy">flame retardancy</a>, <a href="https://publications.waset.org/abstracts/search?q=flammability" title=" flammability"> flammability</a>, <a href="https://publications.waset.org/abstracts/search?q=Pes%2FCo%20blends" title=" Pes/Co blends"> Pes/Co blends</a>, <a href="https://publications.waset.org/abstracts/search?q=polysilicic%20acid" title=" polysilicic acid"> polysilicic acid</a> </p> <a href="https://publications.waset.org/abstracts/43483/a-fr-fire-off-with-polysilicic-acid-for-pesco-blends" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43483.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">415</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> The Effect of Aromatherapy with Citrus aurantium Blossom Essential Oil on Premenstrual Syndrome in University Students: A Clinical Trial Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neda%20Jamalimoghadam">Neda Jamalimoghadam</a>, <a href="https://publications.waset.org/abstracts/search?q=Naval%20Heydari"> Naval Heydari</a>, <a href="https://publications.waset.org/abstracts/search?q=Maliheh%20Abootalebi"> Maliheh Abootalebi</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Kasraeian"> Maryam Kasraeian</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Emamghoreishi"> M.

The assessment in this study went beyond the faithfulness based on repetition, addition, deletion, and creation which limit the analysis from other aspects. In fact, this research aimed to pinpoint the role of multimodality in examining the intersemiotic translations of the novel into film by means of analyzing different applied modes. Through a qualitative type of research, the analysis was conducted based on the theory proposed by Burn as Kineikonic mode theory derived from the concept of multimodality. The results of the study revealed that due to the applied modes, each adaptation represents a sense and meaning different from the other one. Analyzing the results and discussions, it was concluded that not only the modes have an undeniable role in film adaptations, but rather multimodal analysis including different nonverbal modes can be a useful and functional choice for analyzing the intersemiotic translations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cinematic%20adaptation" title="cinematic adaptation">cinematic adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=intersemiotic%20translation" title=" intersemiotic translation"> intersemiotic translation</a>, <a href="https://publications.waset.org/abstracts/search?q=kineikonic%20mode" title=" kineikonic mode"> kineikonic mode</a>, <a href="https://publications.waset.org/abstracts/search?q=multimodality" title=" multimodality"> multimodality</a> </p> <a href="https://publications.waset.org/abstracts/63177/a-multimodal-approach-towards-intersemiotic-translations-of-the-great-gatsby" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63177.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">421</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Pahlevāni and Zoorkhāneh Rituals as Creative Cultural Product in Tourism; Case Study: Isfahan, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neda%20Torabi%20Farsani">Neda Torabi Farsani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mortazavi"> Mohammad Mortazavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Masaeli"> Maryam Masaeli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays intangible heritage as a creative product plays an important role in promoting tourism.

Sampling was done seasonally from spring to winter 2014 from eight sites. Results indicated that of these three species had heterogeneity distribution along southern parts of the Caspian Sea. In addition, C. glomerata was dominant taxa in all stations and had maximum contribution in dissimilarities between sampling sites. According to BIO-ENV salinity, pH and Silicate were the best subset variables for explaining changes in the abundance over time of the hard-substrates macroalgae fauna under study. However, the position of species in Redundancy Analysis (RDA) plot revealed that L. caspica associated with temperature, E. intestinalis with pH and C. glomerata associated with phosphate and silicate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=macroalgae" title="macroalgae">macroalgae</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution" title=" distribution"> distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20factors" title=" environmental factors"> environmental factors</a>, <a href="https://publications.waset.org/abstracts/search?q=Caspian%20Sea" title=" Caspian Sea"> Caspian Sea</a> </p> <a href="https://publications.waset.org/abstracts/39641/distribution-of-laurencia-caspica-enteromorpha-intestinalis-and-cladophora-glomerata-along-the-southern-parts-of-the-caspian-sea-and-their-relation-with-environmental-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39641.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">385</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Seismic Performance of RC Frames Equipped with Friction Panels Under Different Slip Load Distributions </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neda%20Nabid">Neda Nabid</a>, <a href="https://publications.waset.org/abstracts/search?q=Iman%20Hajirasouliha"> Iman Hajirasouliha</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanaz%20Shirinbar"> Sanaz Shirinbar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most challenging issues in earthquake engineering is to find effective ways to reduce earthquake forces and damage to structural and non-structural elements under strong earthquakes.

This research aims to find more appropriate slip load distribution pattern for efficient design of friction panels. Non-linear dynamic analyses are performed on 3, 5, 10, 15, and 20-story RC frame using Drain-2dx software to find the appropriate range of slip loads and investigate the effects of different distribution patterns (cantilever, uniform, triangle, and reverse triangle) under six different earthquake records.

Most jokes are told in slang and common language. In the process of foreign language acquisition, an autonomous learner try to learn the standard language. But there is a colossal divergence between the usage of the different types of language in society. Here, we investigate the french slang and common language and examine the accurate perception of their usage. We illuminate the slang language in the french literature that provide considerably different types of language for an autonomous learner. We provide furthermore evidence from the french novels that demonstrate properly the different types of language and give in one sentence its social meanings. For example, the famous Queneau expression « Doukipudonktant » present the impact of slang language in society. The characters in the novel transfer the slang and the common language and their accurate usages. We present that the language of the autonomous learner depends on the language of the text that is read. Because literature is a vehicle of the culture and the expression demonstrate their real significations and usage in the culture, slang and common language have a crucial role in the culture and all of them are manifested in the oral language. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=common%20language" title="common language">common language</a>, <a href="https://publications.waset.org/abstracts/search?q=french" title=" french"> french</a>, <a href="https://publications.waset.org/abstracts/search?q=humor" title=" humor"> humor</a>, <a href="https://publications.waset.org/abstracts/search?q=slang%20language" title=" slang language"> slang language</a> </p> <a href="https://publications.waset.org/abstracts/131765/the-different-types-of-french-language-in-the-processes-of-acquisition-specifically-about-the-humor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131765.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">238</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> The Role of Product’s Aesthetic Criteria in Customer Behavior: An Approach on Design Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mozhgan%20Sabzehparvar">Mozhgan Sabzehparvar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Montazeri"> Mohammad Montazeri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdie%20Jafarnejad%20Shahri"> Mahdie Jafarnejad Shahri</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Boroumandi"> Neda Boroumandi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shakib%20Alipour"> Shakib Alipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamide%20Torabi"> Hamide Torabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Dehghani"> Zahra Dehghani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, the aesthetic criteria, which are regarded as the key factors in the product development, and design process are carefully taken into account and an attempt has been made to extract the influential concepts in successful product design. This review article was conducted from 22.05.2021 to 22.06.2021, recent published paper in English (2017-2021) in three search engines of JSTOR, IEEE, and EMERALD were selected. The selected main keywords in our search were "Customer, Behavior, Aesthetics, Marketing and Product". During the screenings, 21 articles were analyzed. The aesthetic criteria play a role in increasing the power of choice, loyalty, satisfaction and purchase intention of the customers. Also, product design has a positive effect on the customers’ perception of aesthetics and acts effectively on customer behavior.

The green and blue spaces, including parks, play an important role in meeting those needs, and therefore they should be prioritised in urban planning and designing. Sari city had several city designs and planning projects to expand the green spaces. These included adding more parks and open spaces with new urban furniture in the city and were an important step forward in creating a pleasant urban landscape in the north of Iran. This research used quantitative and qualitative methods to examine whether the citizens of Sari were satisfied with green and blue spaces and new urban furniture in the city or not. From a questionnaire of 120 Sari citizens, it was found that the citizens were generally satisfied with the green and blue spaces and new urban furniture in Sari. It was also found that the favourite park was Mellal park, and the least favourite was Azadegan park. Accessibility, safety, design, facilities, and water source were the most important reason to visit the parks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=satisfaction" title="satisfaction">satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=green" title=" green"> green</a>, <a href="https://publications.waset.org/abstracts/search?q=blue" title=" blue"> blue</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20furniture" title=" urban furniture"> urban furniture</a> </p> <a href="https://publications.waset.org/abstracts/156475/citizens-satisfaction-with-green-and-blue-spaces-and-urban-furniture-in-sari-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156475.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Mineralogy and Classification of Altered Host Rocks in the Zaghia Iron Oxide Deposit, East of Bafq, Central Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azat%20Eslamizadeh">Azat Eslamizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Akbarian"> Neda Akbarian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Zaghia Iron ore, in 15 km east of a town named Bafq, is located in Precambrian formation of Central Iran in form of a small local deposit. The Volcano-sedimentary rocks of Precambrian-Cambrian age, belonging to Rizu series have spread through the region. Substantial portion of the deposit is covered by alluvial deposits. The rocks hosting the Zaghia iron ore have a main combination of rhyolitic tuffs along with clastic sediments, carbonate include sandstone, limestone, dolomite, conglomerate and is somewhat metamorphed causing them to have appeared as slate and phyllite. Moreover, carbonate rocks are in existence as skarn compound of marble bearing tremolite with mineralization of magnetite-hematite. The basic igneous rocks have dramatically altered into green rocks consist of actinolite-tremolite and chlorite along with amount of iron (magnetite + Martite). The youngest units of ore-bearing rocks in the area are found as dolerite - diabase dikes. The dikes are cutting the rhyolitic tuffs and carbonate rocks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zaghia" title="Zaghia">Zaghia</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20ore%20deposite" title=" iron ore deposite"> iron ore deposite</a>, <a href="https://publications.waset.org/abstracts/search?q=mineralogy" title=" mineralogy"> mineralogy</a>, <a href="https://publications.waset.org/abstracts/search?q=petrography%20%20Bafq" title=" petrography Bafq"> petrography Bafq</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran "> Iran </a> </p> <a href="https://publications.waset.org/abstracts/28000/mineralogy-and-classification-of-altered-host-rocks-in-the-zaghia-iron-oxide-deposit-east-of-bafq-central-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28000.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">524</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Polyhydroxybutyrate (PHB): Highly Porous Scaffold for Biomedicine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neda%20Sinaei">Neda Sinaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Davood%20Zare"> Davood Zare</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Azin"> Mehrdad Azin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polyhydroxyalkanoates (PHAs) are biocompatible and biodegradable polymers produced by a wide range of bacterial strains. These biopolymers are significantly studied for drug delivery and tissue engineering applications because of their fascinating physicochemical properties. Polyhydroxybutyrate (PHB) scaffold that has been extracted from a novel bacteria using oil wastewater was selected to study. Some physical parameters affecting scaffold properties such as PHB concentration, solvent evaporation speed, and ultrasonic time were investigated. Scanning electron microscopy was used to evaluate the porosity. Afterward, the biocompatibility of PHB scaffold was assessed. Initial results showed the highly porous PHB scaffold structure with a variety of pore sizes. Subsequent results indicated that more unique pore sizes can be obtained by optimizing physical factors. It would be noticed that the morphology of the pore structure was accordingly affected by ultrasonic time. Hence, In vitro cell viability tests on the PHB scaffold using human foreskin fibroblasts revealed strong cell attachment and proliferation supports. Therefore, it can be concluded that the cost-effective PHB scaffold has the potential using as a biomaterial cell adhesion substrate in therapeutic applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Polyhydroxybutyrate" title="Polyhydroxybutyrate">Polyhydroxybutyrate</a>, <a href="https://publications.waset.org/abstracts/search?q=biocompatible" title="biocompatible">biocompatible</a>, <a href="https://publications.waset.org/abstracts/search?q=scaffold" title="scaffold">scaffold</a>, <a href="https://publications.waset.org/abstracts/search?q=porous" title="porous">porous</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20engineering" title="tissue engineering">tissue engineering</a> </p> <a href="https://publications.waset.org/abstracts/140268/polyhydroxybutyrate-phb-highly-porous-scaffold-for-biomedicine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140268.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">232</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Stereotypes in Perception of Otherness in Balkans Literature from the Last Part of 20ᵗʰ Century</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Kostova-Panayotova">Magdalena Kostova-Panayotova</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda-Maria%20Panayotova"> Neda-Maria Panayotova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article is focused on a problem that tends to be extremely characteristic and essential to European literature – the relations between the Balkan Peninsula and Europe and the stereotypes the Balkans evoke – a melting pot, a powder keg, a bridge, a crossroads, along with other negative definitions. The stereotypes and visions are examined as the layered images of a particular nation. The work deals with the Balkan writers’ way of confronting stereotypes by reversing the image of the ‘dark’ Balkans and the ‘bright’ Europe and thus establishing the Balkans as a place of beauty, music, and poetry. In many aspects, the European image of the Balkans (the so-called Balkanism) is comparable to the European attitude to the Orient (the so-called Orientalism). On the basis of the analysis of specific texts by Balkan authors, the article proves that the identity of the person of the late 20th and early 21st century is something individual and much more complicated than a patriotic self-definition because the identity of the contemporary person is multilayered. It is not flattering to be a bridge, a crossroads or a corner. However, a person is a creature of transition. Our idea demonstrates that the state of transition always brings both weakness and strength – it is the Balkans that connect Europe to the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=image" title="image">image</a>, <a href="https://publications.waset.org/abstracts/search?q=Slavs" title=" Slavs"> Slavs</a>, <a href="https://publications.waset.org/abstracts/search?q=Balkans" title=" Balkans"> Balkans</a>, <a href="https://publications.waset.org/abstracts/search?q=identity%20of%20the%20modern%20Balkan%20person" title=" identity of the modern Balkan person"> identity of the modern Balkan person</a> </p> <a href="https://publications.waset.org/abstracts/96272/stereotypes-in-perception-of-otherness-in-balkans-literature-from-the-last-part-of-20-century" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96272.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Numerical Study on the Ultimate Load of Offshore Two-Planar Tubular KK-Joints at Fire-Induced Elevated Temperatures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Ahmadi">Hamid Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Azari-Dodaran"> Neda Azari-Dodaran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A total of 270 nonlinear steady-state finite element (FE) analyses were performed on 54 FE models of two-planar circular hollow section (CHS) KK-joints subjected to axial loading at five different temperatures (20 ºC, 200 ºC, 400 ºC, 550 ºC, and 700 ºC). The primary goal was to investigate the effects of temperature and geometrical characteristics on the ultimate strength, modes of failure, and initial stiffness of the KK-joints. Results indicated that on an average basis, the ultimate load of a two-planar tubular KK-joint at 200 ºC, 400 ºC, 550 ºC, and 700 ºC is 90%, 75%, 45%, and 16% of the joint’s ultimate load at ambient temperature, respectively. Outcomes of the parametric study showed that replacing the yield stress at ambient temperature with the corresponding value at elevated temperature to apply the EN 1993-1-8 equations for the calculation of the joint’s ultimate load at elevated temperatures may lead to highly unconservative results that might endanger the safety of the structure.

MicroRNAs (miRs) are natural RNA molecules that play an important role in cellular processes and regulate post-transcriptional gene expression. MiR-216b-5p is a miR that acts as a tumor suppressor. The expression levels of FoxM1 and miR-216b-5p in malignant and control cells have been evaluated by quantitative polymerase chain reaction (qPCR) technique and flow cytometry. Results: the results of this study revealed a significant downregulation of miR-216b-5p in cancerous cells compared to the control MCF-10A cells (P=0.0004). Interestingly, the expression of miR-216b-5p exhibited an inverse relationship with key clinical indicators such as tumor size, grade, and lymph node invasion. Conclusion: The study's findings showed the prognostic value of miR-216b-5p levels in breast cancer, and its reduced expression correlates with unfavorable tumor characteristics. This research recommends performing more studies on the role of FoxM1 and miR-216b-5p in breast cancer pathology which potentially paving the way for targeted therapeutic interventions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression" title=" gene expression"> gene expression</a>, <a href="https://publications.waset.org/abstracts/search?q=FOXM1" title=" FOXM1"> FOXM1</a>, <a href="https://publications.waset.org/abstracts/search?q=microRNA" title=" microRNA"> microRNA</a> </p> <a href="https://publications.waset.org/abstracts/185448/investigation-of-foxm1-gene-expression-in-breast-cancer-and-its-relationship-with-mir-216b-5p-expression-level" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185448.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">52</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Analysis of Organizational Factors Effect on Performing Electronic Commerce Strategy: A Case Study of the Namakin Food Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Hamidreza%20Hejazi%20Dehghani">Seyed Hamidreza Hejazi Dehghani</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Khounsari"> Neda Khounsari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Quick growth of electronic commerce in developed countries means that developing nations must change in their commerce strategies fundamentally. Most organizations are aware of the impact of the Internet and e-Commerce on the future of their firm, and thus, they have to focus on organizational factors that have an effect on the deployment of an e-Commerce strategy. In this situation, it is essential to identify organizational factors such as the organizational culture, human resources, size, structure and product/service that impact an e-commerce strategy. Accordingly, this research specifies the effects of organizational factors on applying an e-commerce strategy in the Namakin food industry. The statistical population of this research is 95 managers and employees. Cochran's formula is used for determination of the sample size that is 77 of the statistical population. Also, SPSS and Smart PLS software were utilized for analyzing the collected data. The results of hypothesis testing show that organizational factors have positive and significant effects of applying an e-Commerce strategy. On the other hand, sub-hypothesizes show that effectiveness of the organizational culture and size criteria were rejected and other sub-hypothesis were accepted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electronic%20commerce" title="electronic commerce">electronic commerce</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20factors" title=" organizational factors"> organizational factors</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude%20of%20managers" title=" attitude of managers"> attitude of managers</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20readiness" title=" organizational readiness"> organizational readiness</a> </p> <a href="https://publications.waset.org/abstracts/67393/analysis-of-organizational-factors-effect-on-performing-electronic-commerce-strategy-a-case-study-of-the-namakin-food-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67393.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">280</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> The Comparison of Backward and Forward Running Program on Balance Development and Plantar Flexion Force in Pre Seniors: Healthy Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neda%20Dekamei">Neda Dekamei</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Sarabzadeh"> Mostafa Sarabzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoumeh%20Bigdeli"> Masoumeh Bigdeli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Backward running is commonly used in different sports conditioning, motor learning, and neurological purposes, and even more commonly in physical rehabilitation.

During six weeks, 3 sessions per week, all subjects underwent stated different models of backward and forward running training on treadmill (65-80 of HR max). Pre and post-tests were performed by force plate and electromyogram, two times before and after intervention. Data were analyzed using by T test. On the basis of obtained data, significant differences were recorded on balance and plantar flexion force in backward running (BR) and no difference for forward running (FR). It seems the training model of backward running can generate more stimulus to achieve better plantar flexion force and strengthening ankle protectors which leads to balance improvement in pre aging period.

Cyclic voltammetry (CV) of the electrolyte containing NH₃ indicated mediation of electron transfer by Ni (OH)₂ and the electrode surface was analyzed by X-ray diffraction (XRD), scanning electron microscope (SEM), Raman spectrometer (RS), and X-ray photoelectron spectroscopy (XPS). Results of surface characterization indicated the presence of α polymorphs which is the stable phase of Ni (OH)₂ /Graphite. Cyclic voltammograms gave information on the nature of electron transfer between nitrogen species and working electrode and revealed that the potential has depended on both nature ammonia oxidation and that of concentration. The mechanism of selective ammonia conversion to nitrogen and byproducts, namely NO₂- and NO₃- was established by Cyclic voltammograms and current efficiency. The removal efficiency and selective conversion of ammonia (0.1 M KNO₃ + 0.01 M Ni(NO₃)₂, pH 11, 250°C) on Nickel Oxide-hydroxide /Graphite was determined based on potential controlled experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Electro%20deposition" title="Electro deposition">Electro deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=Nickel%20oxide-hydroxide" title=" Nickel oxide-hydroxide"> Nickel oxide-hydroxide</a>, <a href="https://publications.waset.org/abstracts/search?q=Nitrogen%20selectivity" title=" Nitrogen selectivity"> Nitrogen selectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammonia%20oxidation" title=" Ammonia oxidation"> Ammonia oxidation</a> </p> <a href="https://publications.waset.org/abstracts/132084/selective-oxidation-of-ammonia-to-nitrogen-over-nickel-oxide-hydroxide-graphite-prepared-with-an-electro-deposition-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132084.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> CFD Modeling of Mixing Enhancement in a Pitted Micromixer by High Frequency Ultrasound Waves </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faezeh%20Mohammadi">Faezeh Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Ebrahimi"> Ebrahim Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Azimi"> Neda Azimi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Use of ultrasound waves is one of the techniques for increasing the mixing and mass transfer in the microdevices. Ultrasound propagation into liquid medium leads to stimulation of the fluid, creates turbulence and so increases the mixing performance. In this study, CFD modeling of two-phase flow in a pitted micromixer equipped with a piezoelectric with frequency of 1.7 MHz has been studied. CFD modeling of micromixer at different velocity of fluid flow in the absence of ultrasound waves and with ultrasound application has been performed. The hydrodynamic of fluid flow and mixing efficiency for using ultrasound has been compared with the layout of no ultrasound application. The result of CFD modeling shows well agreements with the experimental results. The results showed that the flow pattern inside the micromixer in the absence of ultrasound waves is parallel, while when ultrasound has been applied, it is not parallel. In fact, propagation of ultrasound energy into the fluid flow in the studied micromixer changed the hydrodynamic and the forms of the flow pattern and caused to mixing enhancement. In general, from the CFD modeling results, it can be concluded that the applying ultrasound energy into the liquid medium causes an increase in the turbulences and mixing and consequently, improves the mass transfer rate within the micromixer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD%20modeling" title="CFD modeling">CFD modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=mixing" title=" mixing"> mixing</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20transfer" title=" mass transfer"> mass transfer</a> </p> <a href="https://publications.waset.org/abstracts/102598/cfd-modeling-of-mixing-enhancement-in-a-pitted-micromixer-by-high-frequency-ultrasound-waves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102598.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Effects of Geometrical Parameters on Static Strength of Tubular KT-Joints at Fire Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Ahmadi">Hamid Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Azari%20Dodaran"> Neda Azari Dodaran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to study the structural behavior of tubular KT-joints subjected to axial loading at fire induced elevated temperatures. At first, a finite element (FE) model was developed and validated against the data available from experimental tests. Then, a set of 810 FE analyses were performed to study the influence of temperature and dimensionless geometrical parameters (β, γ, θ, and τ) on the ultimate strength and initial stiffness. The joints were analyzed under two types of axial loading and five different temperatures (20 ºC, 200 ºC, 400 ºC, 550 ºC, and 700 ºC). Results show that the ultimate strength and initial stiffness of KT-joints decrease considerably by increasing the temperature. In the joints having bigger values of the β, the temperature elevation leads to less reduction in ultimate strength; while in the joints with bigger values of the γ, the temperature elevation results in more reduction in ultimate strength. The influence of the θ on the ultimate strength is independent from the temperature. To our knowledge, there is no design formula available for determining the ultimate strength of KT-joints at elevated temperatures. Hence, after parametric study, two equations were developed through nonlinear regression, for calculating the ultimate strength of KT-joints at elevated temperatures. <p
